Python脚本不会运行在SSH上，但会在本地运行

Question

我正在编写一个小应用程序来监视使用覆盆子pi的一些温度。我希望能够远程启动或重新启动监视脚本。我通过SSH连接，cd连接到.py文件的目录，然后我“python temp_controller.py &”。这给我一个导入错误的错误。 “从w1thermsensor进口W1ThermSensor”。在Pi上直接从Thonny运行脚本时，不会发生此错误。

“主”文件。

我想你的本地机器上做了类似pip install w1thermsensor的东西吧？您还需要在您的Raspberry pi上安装w1thermsensor依赖关系
